Nabil has a balance of $3,000 on his credit card. Assume he only makes the minimum required payment of $90 on this balance every month until the card is paid off. Assume also that no new purchases are made with this card. The interest rate charged on the card is 18% per annum, compounded daily. How much total interest will he have paid on his card by the time the $3,000 is fully paid off?
